Additional Info: Lamda system mandatory?

["content22207" <brobertson@xxxx>]

Bosch ID tag on my fuel distributor reads: 438 100 092.

Have no idea how that compares to a DeLo unit, but is obviously a
Jetronic system of some ilk. FWIW *ALL* parts purchased from vendors
have installed perfectly, including injector seals. I suspect R30
isn't too far removed from a factory block.
